Description
General information
The Porsche System Tester 2 is a modular, portable diagnostic and measuring system. It can be used in any location to perform diagnostic tests on electronic control modules.
The Tester consists of a computer unit, a main memory, a hard disk, a VGA display panel, a nickel metal hydride battery and a measuring unit for measurement of current, voltage and resistance values.
The Porsche System Tester 2 can be operated with the built-in keys or using a connectable country-specific PS/2 keyboard (option).
Data and measured values can be printed out on one of the ten DIN A4 printers currently approved by Porsche.
The integrated LCD panel is used as the display. A monitor can also be connected (VGA connection).
If a printer or PS/2 keyboard is connected, the corresponding device type must be set under Configuration in the start-up screen.
The Tester thus can be used to check all systems that possess a diagnostic interface conforming with the ISO standard.
The following tasks can be performed:
- Reading out the control-module identification
- Reading out the fault memory
- Erasing the fault memory
- Testing the drive links
- Testing the input signals
- Reading out actual values
- Control module programming
- Current, voltage and resistance measurements
Malfunctions
The Porsche System Tester 2 is a high-quality electronic device. In order to prevent damage to the unit due to improper use, please observe the operating instructions.
If the Tester no longer responds when any key is pressed, it must be set to a defined state:
1. Press the F1 and F8 keys in addition to the "ON/OFF" key.
2. Release the "ON/OFF" key, then the F1 and F8 keys.
Perform this switch off procedure only if the unit no longer responds when any key is pressed. This procedure can damage the hard disk under certain circumstances if it is performed during normal operation. It may be necessary to repeat input of data created within this diagnostic application.
Problems during operation are indicated to the user via the information line (info line). Example: "Diagnosis Card not inserted".

Connections
NOTE: Before current, voltage or resistance measurements: Use the ground lead to connect the ground socket (1) to the vehicle ground point prior to connecting the diagnosis lead.
Diagnosis Card
The Diagnosis Card is the interface between the Porsche System Tester 2 and the vehicle.
The Diagnosis Card is responsible for the diagnosis reports, control-module programming voltage and for voltage supply to the Porsche System Tester 2 via the vehicle battery.
The Diagnosis Card can be left in the Tester.
Voltage supply
Three types of voltage supply are possible for the Porsche System Tester 2:
- Internal rechargeable battery (operating time approx. 20 min)
- Vehicle battery (supply via plugged-on diagnosis lead, Diagnosis Card)
- Mains power supply.
Before putting the unit into operation, make sure that the mains voltage and the voltage specified on the mains power supply unit are the same.
Adjusting illumination of LCD panel
Press key 2.5 and key 2.4 --> Display brighter
Press key 2.5 and key 2.6 --> Display darker
Working log
During diagnosis, e.g. when the fault memory is being read out, a "save" symbol appears near the softkeys. This item is saved in the working log if the corresponding softkey is pressed.
The working log can be printed out with key 2.3. It is thus possible to document all stored faults, for example.
Starting diagnosis
1. Connect the Porsche System Tester 2 to the diagnostic socket (data link connector) in the vehicle.
2. Switch on the Porsche System Tester 2 (it will be ready for operation in approx. 60 seconds).
3. Switch on the ignition.
4. Select the vehicle type and initiate diagnosis with key 2.14.
The Porsche System Tester 2 starts to search for control modules and then lists all control modules it finds. Control modules that are not installed (e.g. Tiptronic control module on vehicles with manual transmission) are displayed in grey.
NOTE:
If no control modules are detected, check whether the ignition is on or whether terminal 15 is present on the diagnostic socket.
If faults are stored in a control module, this is identified with the # symbol as before.
Automatic switch-off
The Porsche System Tester 2 switches itself off after an Off delay if
- no voltage is supplied via the mains power supply unit or via the vehicle battery
or
- no data are being transferred via an interface (no key pressed, no communication with control module).
The Off-delay time can be changed in the Configuration menu. The default Off-delay time is 3 minutes.
Automatic switch-off is preceded by a rhythmic beeping sound (10 seconds). The Porsche System Tester 2 will remain switched on if the mains power supply is connected or a key is pressed within this time.
Software update
The software can be updated using the supplied CD-ROM drive.
1. Connect CD-ROM drive with the Porsche System Tester 2.
2. Connect Porsche System Tester 2 and the CD-ROM drive to the mains power supply unit.
3. Load CD-ROM in the drive and close the drive.
4. Switch on the Porsche System Tester 2.
5. Select "Software installation" in the Configuration menu.
